macos-aarch64 build error, I have been encountering this problem for the past two days. How do I solve it?

Run # On macOS we need to install some dependencies for testing
  # On macOS we need to install some dependencies for testing
  brew install make
  sudo xcode-select --switch /Applications/Xcode_14.3.1.app/Contents/Developer
  # This will make GNU make available as 'make' and not only as 'gmake'

==> Caveats
GNU "make" has been installed as "gmake".
If you need to use it as "make", you can add a "gnubin" directory
to your PATH from your bashrc like:

    PATH="/opt/homebrew/opt/make/libexec/gnubin:$PATH"
